Title: Telescope equipped with tripod mount
Inventor: ISHIKAWA YASUAKI
IPC: G02B23/16
Filed: 1998-07-02
Abstract: PROBLEM TO BE SOLVED: To make the operability excellent and to rapidly cope with a careless operation by arranging a tripod mount in a telescope main body on an objective lens side from the position of the center of gravity of a telescope. SOLUTION: A focus ring 4 driving and focusing a focus lens group is rotatably fit on the outer periphery of the nearly center part of a single lens telescope while its movement in the optical axis direction is regulated. The tripod mount 5 is also provided on the lower part of the telescope main body 1a of the telescope between the ring 4 and an ocular part 3. As for the balance position (center of gravity) of the telescope at such a time, the tripod seat 5 is positioned closer to an image side, that is, on an ocular side. Thus, even when a universal head operation handle 8a is carelessly unfastened in the state that it is fixed to a tripod 8, since the telescope falls down to an operator side, that is, a rear side, it is much more easily held than when it falls down to the opposite side and the telescope is protected from an accident.  Further, since the ring 4 is positioned on the front side of the operator who operates the tripod 8, focusing operation is very easily performed.

Title: Laser recording device
Inventor: MURAHASHI TAKASHI
IPC: H04N1/113
Filed: 1985-08-29
Abstract: PURPOSE:To vary the diameter of a spot of a semiconductor laser beam on a recording medium with a simple constitution by changing the optical intensity of the laser beam in accordance with recording magnification. CONSTITUTION:The electric potential VA of a point A is changed in accordance with the recording magnification. Namely, since the VA is increased and the output voltage of a comparator 17 is reduced in accordance with the increase of the recording magnification, the collector current of a transistor (TR) 14 is increased and the diameter of a spot is increased. When the recording medium is decreased on the contrary, the VA is reduced, the output voltage of the comparator 17 is increased, the collector current of the TR 14 is reduced, and 17 is increased, the collector current of the TR 14 is reduced, and the driving current of a semiconductor laser 13 is reduced. Consequently, the optical intensity is reduced and the diameter of the spot is reduced. Since the driving current of the laser 13 is continuously changed by continuously changing the recording magnification, the diameter of the beam spot is also continuously changed.

Filed: 1994-08-10
Abstract: PURPOSE:To obtain a vacuum enclosure in which a magnetic fluid can be used under a state equivalent to stationary field by a structure wherein the pole, the permanent magnet and the housing follow the rotation of rotary shaft integrally. CONSTITUTION:In order to rotate a vacuum enclosure 14, a vacuum sealing means 9 fixed to an evacuation hole 8 is fixed with an evacuation pipe 10. The vacuum sealing means 9 functions to evacuate the vacuum enclosure 14 coupled with a communication hole of a rotary shaft 1 and then the evacuation pipe 10 is removed from the vacuum sealing means 9. In this regard, a shaft seal mechanism receiver 4 comprising a magnet 6, poles 2, 3 and a magnetic fluid 7 follows the rotation of the rotary shaft 1. Consequently, the difference of r.p.m. is decreased between the rotary shaft 1 and the poles 2, 3 and since friction and stir of the magnetic fluid are reduced, the magnetic fluid can be used under a state equivalent to stationary field. This structure eliminates the need of providing a groove for carrying a refrigerant at a pole in order to suppress heating of the magnetic fluid as well as the need of a refrigerant carrying system.

Abstract: PURPOSE:To prevent the dependency of the distance measuring capability upon the temperature by changing a ratio of the drop voltage from the breakdown voltage of an avalanche photo diode (APD) in accordance with the ambient temperature. CONSTITUTION:Capacitors 18 and 19 whose temperature capacity change characteristics are positive and 0 respectively and a first FET 12 perform the voltage drop operation. When capacity values of capacitors 18 and 19 are C1(T) and C2(T is the ambient temperature) respectively, a ratio of the voltage applied to the capacitor whose temperature capacity change characteristic is 0 is C2 :C1(T). Consequently, the charging voltage is dropped by the voltage applied to the capacitor, whose temperature characteristic is positive, at the time of earthing the capacitor 19 by an FET or the like, and its drop rate Z has a higher value at a lower temperature as shown by C1(T1)<C1(T2) for C2/C1(T)+ C2(T1<T2). After an APD 15 causes a breakdown phenomenon, the timing signal of a breakdown detecting circuit 17 is switched from the low level to the high level, and the FET 12 is turned on, and the capacitor 18 is earthed, and the voltage dropped by the drop rate Z is applied to the APD 15.
